Robbers got away with cash when they attacked a security guard outside a bank in Shifnal this afternoon.
The robbers are thought to have got away on a motorcycle after the raid outside the Lloyds TSB branch in Park Street just before 2pm.
The G4S driver was left shaken but unhurt.
The raid follows a similar attack on the nearby Barclays Bank in August.
West Mercia Police spokesman Chris Ammonds said the driver had been into the bank and was returning to his van when two men approached and demanded the cash box.
He said: "They grabbed the box from him and made off in the direction of the A41 on a motorcycle.
"It is not known at this stage how much money was in the box and inquiries are continuing."
He said officers were liaising with the Central Motorway Police Group and West Midlands Police to search possible escape routes for the robbers.
The two men are described as wearing dark motorcycle leathers and dark helmets.
A spokesman for G4S said: "The driver is extremely shaken but unharmed."
Mr Ammonds appealed for any witnesses to the robbery or anyone who saw two men dressed in motorcycle clothes hanging around near the bank to contact police on 101, quoting incident number 294S081013.
